Background:
There is growing awareness of an association between cardiovascular disease (CVD) and fractures, and a temporal increase in fracture risk after myocardial infarction has been noted but the mechanisms are not delineated. To evaluate this relationship, we systematically examined the association of hip fracture with all disease categories and assessed related secular trends.
Methods:
Using resources of the Rochester Epidemiology Project, a population-based incident case-control study was conducted. Disease history was compared between all Olmsted County, Minnesota, residents aged 50 years or older with a first hip fracture in 1985–2006 and community control subjects individually matched (1:1) to cases on age, sex, and index year (n=3,808; mean age [SD], 82 [9] years; 76% women).
Results:
All CVD and numerous non-CVD categories (e.g., infectious diseases, nutritional and metabolic diseases, mental disorders, diseases of the nervous system and sense organs, and diseases of the respiratory system) were associated with fracture risk. However, increasing temporal trends were almost exclusively detected in categories of CVD (Figure). The largest increases in association were observed for ischemic heart disease, other forms of heart disease (including heart failure), hypertension, and diabetes and were more pronounced among elderly women than other demographic groups.
Conclusions:
While the association with hip fracture was not specific to CVD, temporal increases were mainly detected in cardio-metabolic diseases, all of which have also been linked previously to frailty. This could delineate a common pathway that warrants further investigation.
